### 1 - 1 1.0 I NTRODUCTI ON



### The purp ose of thi s documen t is to provi de guid

ance to St ates in se tting re asonable

progre ss goals

(RPGs) as

part of th eir regional haze state impl ementati on plans ( SIPs) and in deciding those mea sures ne cessar

y to meet thes e goals . We empha size that th is docume

nt is merely guidan ce and th at States o r the Envi ronmenta l Protecti on Agen

cy (EPA) ma

y e lect to follow or deviate from this guidance, as appropr iate. The ultimate determination of whether a given SIP submission by

a State meets the statutory r equirements of sections 169A and 169B of the Clean Air Act (CAA) and the reg ional haze regulations at 40 CFR 51.300 - 309 will be accomplished through notice and comment rulemaking in which the facts and circumstances of each State submission will be evaluated by EPA.

Under the Tribal Authority Rule, 40 CFR part 49, Tribes have the authority to seek “treatment as a State” for purposes of administering certain CAA programs, including the region al haze pr ogram. Whether T

ribes se ek this au

thority or not, EPA

encoura ges Tr ibes to participate in the regional planning e fforts to address visibility and to consult with neighbor ing States as they deve lop their regional haze SIPs. We hope that this guida nce will provide Tribes with an understanding of the process for e stablishing RPGs that will assist them in the
consulta tion proc ess.

1.1 Legislative and Regulatory History

The CAA was amended in August 1977, and a new section 169A was added for the
protect ion of visib ility

in mandat

ory class I Feder al area s (Class I

areas) of gre at sceni c importanc e. I

n section 169A(a) (1), Cong

ress esta blished th e nationa

l goal f or visibili ty protect ion:

Congress hereby declares as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory class I Federal areas which impairment results from manmade air pollution.

Section 16 9A(a)(

4), in par t, requir es EPA to “

promulg ate reg

ulations to

assure r easonab le

progre ss toward

meeting the natio nal goa

l.” The CA

A also re quires Sta

tes to submi

t SIPs containing such emission limits, schedules of compliance, and other measure s as may be

necessa ry to make r

easonab le prog

ress towa rd meetin g the g oal. 1

der [sec tion 169A], i

ncluding criteri a for me asuring

‘reaso nable progress’ toward the national g oal.”

In response to these mandate s, EPA promulgated the regional haze rule ( RHR) on July 1,

1999. 2 

### Under se ction 51.3 08(d)(1 ) of this r ule, State s must “est

ablish g oals (expr

essed in
decivie ws) that p rovide f

or reas onable pr

ogress towards a

chieving natural visibility condition s”
for eac h Class I area w ithin a Stat

e. These RPGs must pr

ovide for an improv ement in v isibility for the most impaired day s over the period of the implementation plan and ensure no deg radation in visibility for the least impaired day s over the same period. 3



### The RHR also requires States to submit a long-term strategy that includes such measures

as are necessary

to achieve the RPG for each Class I area. 4 

### The reg

ulations r equire St ates to consider major and minor stationary sources, mobile sources, and area source s in developing their long-term strategies. I n addition, States must submit a SIP that contains either emission

### 1.2 Meaning of t he Term “Reasonab le Pro gress G oal”

States must establish RPGs, measured in deciviews (dv), for each Class I area for the purpose of improving visibility on the haziest day s and ensuring no degrada tion in visibility on the clearest day s over the period of each implementation plan. 7

### In determining wha

t would constitute reasonable progress, section 169A(g ) of the CAA require s States to c onsider t he follow ing four factor s:

• The costs of compliance;

• The time necessary for compliance;

• The energy

and non-air quality e

nvironmental impacts of compliance; and

• The rema

ining use ful life o f existing sources that cont ribute to v

isibility impairme

nt. 9



### States must demonstrate in their SIPs how these factors ar e taken into consideration in selecting
the RPG for each Class I ar ea in the State.

The discussion of the statutory fa ctors in this guidance is largely aimed at helping States apply these fa

ctors in considering measures for point sources. States may find that the factors
can be a pplied to s ources o ther tha n point sour

ces; the meaning of the fa ctors, ho wever, should not be unduly strained in order to fit non-point sources. In other words, if c ommon sense dictates that a particular statutory

factor cannot be applied to a particular sour ce category

, then the State’s analysis may

reflect that fact, and emissions reductions from such source s may still be included
in the SI P.

As noted above, the RHR establishes an additional analy tical requirement for States in the process of establishing the RPG. This analy tical requirement requires States to determine the
rate of improveme

nt in visibil ity needed to

reach natural c onditions b y 20 64, and to set eac h RPG taking t his “gli depath”

into acc ount. 10 

### (The process for determining the g lidepath is discussed later in this document.) EPA adopted this approach, in part, to ensure that States use a c ommon analy tical fr amework that acc ounts for

the reg ional diff

erence s affec ting visib ility and, in pa

rt, to ensure an informed and equitable decision making process. The glidepath is not a presumptive
targe t, and Stat

es may establish a RPG that p rovides f

or gre ater, le sser, or

equivale nt visibility improvement as that described by the glidepath.

### 1 - 4 In deciding wha

t amount of emissions reduction is appropriate in setting the RPG, y ou should take into account the fact that the long-term g oal of no manmade impairment encompasses several planning periods. I t is reasonable for y

ou to defer reductions to later planning periods i n order t o maintain

a consist ent glid epath tow ard the l ong-te

rm goal

.

1.3 Relationship of Reasonable Progress to BART and the Long-Term Strategy

The RPGs, the long-term strategy , and BART (or alternative measures in lieu of B ART) are the three main elements of the reg ional haze SIPs that States are required to submit by December 17, 2007. The long-term stra tegy and BART emissions limitations or other alternative measures, including cap-and-tra de programs or other economic ince ntive approaches, are
inheren tly r elated to the RPG. Th e long- term stra tegy is the comp ilation of

“enfor ceable emissions limitations, compliance schedules, and other measures as necessar y to achieve

the [RPGs],” 11 

### and is the

means thr

ough wh ich the Sta

te ensur es that its RPG will be m et. BART
emissions l imits (or a

lternati ve measu res in lie u of BART , such as t

he Clean Air I nterstat e Rule (CAIR)) are one

set of measures that must be included in the SIP to ensure tha t an area makes reasonable progress toward the national goal, and the visibility improveme nt resulting from BART (or a BART alternative) is included in the de velopment of the RPG.

### O F THE 

### P ROCESS FOR 

### D EVELOPING THE 

### RPG

Development of the RPG for each Class I area should be a collaborative proce ss among State, local, and Tribal authorities, Regional Planning Org anizations (RPOs), and FLMs. Steps
for deve loping RPG s will be br iefly outlined in

this secti on of the g

uidance , along

with references to other guida

nce and rules where additional detail can be found. The remaining
sections of this g uidance expand on p articula

r aspec ts of these

steps. I n addition , as this is guidance for States in developing RPGs, the use of “ you” throug

h the rest of the document refers

to States.

2.1 Establish Bas eline and Na tural Visi

bility Condit

ions

To track progre ss toward

the natio nal goa

l, the RHR, a

mong othe

r things , requir

es y ou to
establish the “bas eline co nditions” repres enting v

isibility for the b est and w orst day s at the tim e the regional haze program is established f or each Class I ar

ea. Once established, the baseline

repres ents the s tarting

point fro m which re asonable progre ss will be me asured. The RHR al so require s yo

u to estima

te “natu ral cond itions” fo r each C lass I

area th at repr

esents th e visiblity
condition s that woul d exist in the absence of man-ma

de impair ment.

As explaine d in the RHR, the base line for e ach Class I ar ea is the averag e visibility

(in dv) for the 20 percent most impaired day s, or “worst day s”, and for the 20 percent least impaired days, or “be st days,” for the years 2000 throug

h 2004. 12 

### Using available monitoring data for the 2000 to 2004 time period, you are required to calculate the baseline by averaging the annua

l values (in dv) for the 20 percent worst day s in each ye ar (yr

) to produce a single value (in dv) that represents the baseline conditions for the worst day s. You should follow the same approach for determining the value that represents the base line conditions for the best days. Na tural
conditions at each Class I are a are also expressed by reference to the level of visibility (in dv) for the 20 per

cent most i

mpaired and leas t impaire d day s. 13

Figure 1 2.2 Deter mine the

Glidepat h, or Unifor m Rate of Progr ess

By compa

ring baseline conditions with natural conditions, y ou can determine the uniform rate of visibility improvement, or prog ress, needed to reach natural conditions by 2064 for each Class I area. Fig

ure 1, below, illustrates the basic steps in the process for calc ulating the uniform
rate of progre ss toward

natural condition s for the

first pla nning pe riod at a hyp othetica

l Class I

area.

Figure 1 Exam ple of a U niform Rate of Pro gress



### • Compare baseline conditions to natural conditions. The difference be tween these two

repres ents the a

mount of pr

ogress needed to reac h natura

l visibility

condition s. In

this example, the State has determined that the baseline for the 20 perce nt worst days for the
Class I area is 29 dv and estimated that na tural background is 11 dv, a differenc e of 18
dv.

• Calculate the annual average visibility improvement needed to reac h natural conditions by 2064 by

dividing the total amount of improvement needed by 60 years (

the period between 2004 and 2064). I n this example, this value is 0.3 dv/yr.

### Guidance for Setting Reasonable Progress Goals Under the Regional Haze Program

2 - 3

• Multiply the annual avera ge visibility improvement nee ded by the number of years in the first planning period (the period from 2004 until 2018). I n this example, this value is 4.2 dv. This is the uniform rate of progress that would be neede d during the first planning period to attain natural visibility conditions by 2064.

If y ou were to achie ve this ste ady

improveme

nt in visibil ity o ver the n ext 60 y ears, y ou would reach the national goal by 2064.

2.3 Identify and Analyze the Measures Aimed at Achieving the Uniform Rate of Progress.

The next step in setting an RPG is to identify and analy ze the measures aimed at
achievi ng the u niform ra te of pro gress a

nd to dete rmine whe

ther the se measu

res are reasona ble based on the statutory f

actors identified in Section 1.2 above. To meet this requirement, we

sugge st the foll owing a

pproach which en sures tha

t States consider a

ll reason able mea sures in developi ng their region al haze SI

Ps:

• Ide

ntify the key pollutants

and sourc es and/or

source c ategor

ies that a re contr ibuting t o visibility impairme

nt at eac h Class I area. T he sourc es of impa

irment fo r the most impaired and leas t impaire d day s may differ. Section 3 d

iscusses this proc ess.

• Ide

ntify the contr ol measur es and as sociate d emission r eduction s that are

expected to
result fr om complia

nce with e

xisting rul es and

other available measures for the source s and sourc e categ ories tha t contribu te signi ficantly

to visibility

impairme

nt. This is
covered in more detail in Section 4.

• Determine what additional control measures would be rea sonable based on the statutory
factors and other relevant fac tors for the sources and/or source cate gories y ou have
identified.

• Estimate t

hrough the use of

air qual ity m

odels the improveme

nt in visibil ity t

hat would result from implementation of the control measures y ou have found to be reasonable and

compare this to the u

niform ra te of pro gress.

Another possible approach that some States and RPOs are using is to “bac k out” the

measures necessary

to achieve the uniform rate of progr ess. In this process, States are using dispersio n modeling

to estimat

e the visib ility

impacts of

a specif ic perc entage

reducti on in visibility impairing pollutants. The resulting visibility conditions are then compared to the
unifo rm rat e of pro gress. Using t his p rocess , Sta tes wi ll be a ble to ident ify a percen tage

### 2 - 4 reduction in visibility impairing pollutants that would provide prog ress at or bey

ond the uniform rate of progress. I

n a separate step, States would consider the statutory factors along with other relevant factors to select appropriate me asures to achieve the identified reduction in emissions. States can thus identify the mea sures that would be needed to achieve the uniform ra te of progress at a Class I

area and determine whether suc h measures are reasonable.

2.4 Estab lish a RPG

In developing a RPG, y

ou must consult with other States with emissions sources that may reasonably

be anticipated to cause or contribute to visibility impairment at Class I areas in y our State. 14 

### The regulations anticipate that States may not always ag

ree on what measures would be reasonable or on the appropriateness of a RPG. We encourage States to work together e arly and often to resolve such issues. In addition, the F LMs may provide insight and assistance to States in identifying re gional approaches to address the RPG.

The improvement in visibility resulting from implementation of the me asures you ha ve found to be reasonable, considering the unifor m rate of progress, is the amount of prog ress that

repres ents y

our RPG. Th e regi onal haze rule re quires y

ou to clea rly support y

our RPG determination in your SI

P submission based on the statutory factors. 15

### This process begins with the identification of key pollutants and source categories that contribute to visibility impairment at the Class I area. Such analy sis has been the subject of
consider able stud y ov er the pa st decad

e, includ ing studi es by

the Gran d Cany on Visibilit

y Transpo rt Commissio n and ong oing wor k by RPOs. For

the purpo se of this d

ocument, it is assumed that analyse s identifying the ke y pollutants contributing to visibility impairment have
been conducted for each Class I area.

3.1 Identificat

ion of Source

Categor ies Fro m Which The se Pollut ants and Their

Precursors Are Em itted

Once the key

pollutants contributing to visibility impairment at each Class I area have been identified, the sources or source ca tegories responsible for emitting these pollutants or pollutant precursors can also be determined. There are several tools and techniques being employed by

the RPOs to do so, including analysis of emission inventories, sourc e apportio nment, tra

jectory analy sis, and a tmospher ic modelin

g. Technical g

uidance on these t

ools and techniques is bey

ond the scope of this document. Instead, this document foc uses on policy
considerations relevant to the identification of which source c ategories should be considered as part of the regional haze SI P development process.

When identifying the sourc es or source categories r esponsible for regional haze, y ou should consider the relationship between the RPG and the requirements for long -term strategies. The reg ulations r equire St ates to c onsider m ajor and minor stat

ionary sources , as well a s mobile
and are a source s, in deve loping lo ng-ter m strateg ies. 16 

### At a minimum, the regulations require
you to con sider severa l fact ors wh en dev elopi ng a lon g-term strat egy, inclu ding t he fol lowi ng:

• Emissions reductions due to ongoing air pollution control programs, including measures to address reasonably attributable visibility impairment and those taken

### There are numerous possible conceptual appr oaches that you c an use to identify control measures for the long-term strateg y and the re lated RPG. We suggest beginning by concentrating on possible

emissions r

eduction s of seve

ral pollut ant spec ies from a

few sele cted sour

ce sect ors, focusing on those so

urce ca tegori es that ma

y ha ve the g reates t impact on

visibility at Class I areas, considering cost and the other factors discussed further in Section 5.0.

4.1 Consideration of Emissions Reductions from State, Federal, and Local Control

Measures

One impor

tant fac tor to kee

p in mind whe

n establis hing a RPG

is that y ou canno t adopt a RPG that represents less visibility improvement than is expected to result from the implement

ation of o ther CAA r

equirem ents. 18 

### You must therefore determine the amount of
emission r

eduction s that ca

n be expec ted from i dentifie d source s or sourc e categ ories as a result of requirements at the local, State, and federa l levels during the planning period of the SI P and the resulting improvements in visibility at Class I areas. Given the significant emissions reductions that we anticipate to result from BART, the CAI R, and the implementation of other CAA prog

rams, inc luding th e ozone an d PM 2.5 

### NAAQS, for many States this will be an important step in de

termining you r RPG, and

it may be all tha t is nece ssary

to achie ve reas onable progress in the first planning period for some States.

The first step in this process is to identify the base line emissions inventory y ear on which
your strateg

ies are based. For the first RHR SI P, we anticipate that States will use 2002 as the
baseline ye ar for e

mission inve

ntories. 19 

### If you do use 2 002, you m ay take cred it in your longterm strategy

for emission reductions achieved after 2002. This includes emission reduc tions
from mea sures impl emented to attain t

he ozone a

nd PM 2.5 

### NAAQS, 20 

### and Federal progra ms, such
as the na tional mobi le sourc e prog ram and f ederal standar ds for ha zardous a ir polluta nts (air toxics).

Identified

After de termining the amoun

t of emissi ons reduc

tions of vis ibility

impairing

pollutants that may be expected f

rom implementation of other CAA programs, y ou will be ready to identify any additional measur

es that are reasonable. The RHR give s States wide latitude to determine additional control requirements, and there are many ways to approa

ch identifying

additional reasonable measures; however, y ou must at a minimum, consider the four statutory fa ctors.
Based on the contribution from certain source c ategories and the magnitude of the ir emissions

you may determine that little additional analysis is require d to determine further controls are not

warran ted for th at cate gory . As discu ssed fur ther in se ction 5, y

ou have c onsidera

ble flexibi lity in how y ou take th ese fac

tors into c onsidera

tion. I n addition

to source -specif

ic contr ols, emissions cap-and-trade progra ms may be considere d. Sources of information on control techniques for specific source cate gories include the RACT/BACT/LA ER Clearinghouse and
EPA’s AIRControlNet database. 21



### One appr oach tha t yo u could ta ke to stre amline wh at could b e an extre mely complex tas k would be to first identify alterna tive control scenarios with different levels of stringe ncy. Eac h control scenario would assume application of specific control leve ls or measures to the sources or source categories y

ou have identified as the significant sources of visibility impairment. As
indicate d previou sly

in section

4.1, the st

arting point for this asses sment is the

visibility improvement achieved as a result of BART, the CAI R, and the implementation of other CAA

progra ms, includ

ing othe r measur es for a ttainment of the ozon e and PM 2.5 

### NAAQS. Yo u would then consider whether any additional control scenarios are reasonable ba sed on your
consider ation of th e statutor

y f actors a nd any other fa ctors y ou have d etermine d are re levant.

Another approac h yo u could ta ke, cons istent with

the “bac k out” app

roach di scussed i

n section 2.3, would involve identifying the set of emissions control measures that achieves the
target percentag e reductions in visibility-impairing pollutants associate d with progress at or beyond the uniform ra

te of progress. The selection of control mea sures to include in this set would be guided by

your considera

tion of the statutory fac tors and any other factors you ha

ve determin ed are r

elevant

.

Note that for some sources determined to be subject to BART, the State w ill already have completed a BART analy sis. Since the BART analy sis is based, in part, on an assessment of

many of the sa me factors that mus t be addr essed in e stablishin

g the RPG , it is rea sonable t o

conclude that any

control requirements imposed in the BART determination also satisfy the RPG-related requirements for source re view in the first RPG planning period. Hence, y ou may conclude that no ad

for thes e source s in the first planning period.

### In de termining reasona ble prog ress, CAA

§169A(g )(1) re quires Sta

tes to take

into
consider ation a nu mber of f actors. Howeve

r, y ou have f lexibility in how to ta

ke into consideration these statutory factors and any

other factors that y

ou have determined to be relevant. For example, the factors could be used to sele ct which sources or activities should or
should not b e regu

lated, or they could be u sed to det

ermine th e level o r string ency of contr ol, if any, for se lected sources or activities, or some combination of both. The fac tors may be considered both individually and/or in combination. As noted in sec tion 4.1, given the significant emissions reductions that we anticipate to result from BART, the CAI R, and the implementation of other CAA programs, these reductions may be all that is necessary

to achieve

reasona ble prog ress in the

first pla nning pe riod for some State s. Also, a s noted in s ection 4. 2, it
is not nec essary

for y ou to rea ssess the

reasona ble prog ress fa ctors fo r source s subject

to BART
for whic h yo u have a lready complete d a BART a

naly sis.

5.1 Reasonable Progress Statutory Fact or (a): Costs of Compliance

The first factor to take into consideration is the “costs of compliance .” In this context we believe that the cost of compliance factor ca n be interpreted to encompass the cost of compliance
for indiv idual sour

ces or so urce ca tegori es, and mo re broa

dly the implic ation of c omplianc e costs
to the hea lth and vita

lity of industr

ies within a state. For add

itional g uidance on apply ing the c ost of complia

nce fac tor to stat ionary sources , yo

u may wish to con sult the B ART guid elines,
referenced above.

To assess compliance costs for individual sources or source c ategories potentially subject to emission limitations, we suggest that you use established control cost analy sis techniques. For
stati onary sou rces, ge nerall y this in volv es the follo wing: 22



### a) Identify

the emissions units to be controlled;

b) Identify

the design parameters for emissions controls; and

c) Develop

cost estim ates bas ed upon th ose desig n parame ters.

### Guidance for Setting Reasonable Progress Goals Under the Regional Haze Program

23 Any additional inf

ormation used for the cost cal culations, including any information suppli ed by vendors

that aff ects your ass umpti ons r egardi

ng pur chas ed equi pment cost s, equipme nt l if e, r eplac ement

of maj or components, and any ot her el ement of the cal culat ion th at dif fers from th e Co ntrol C ost M anu al, shoul d be

docu mented . EPA ’s Control Cost Manual

is locate d at: www.e pa.go v/ttncatc 1/pr odu cts.html# cccin fo

.



### 5 - 2 You should evaluate both average a nd incremental costs. To maintain and improve consistency
wherev er possib le, cost e stimates s hould be b ased on E PA’s Air Pollutio n Control Cos t Manual

. 23



### In considering the c ost of compliance factor, y ou should keep in mind that different pollutants differently impact visibilityimpairment. For example, on a ton basis, sulfur dioxiderelated particles have a gr eater impact on visibility impairment than cr ustal material. Therefore,
in ass essin g addit ional emiss ions reduct ion s trate gies fo r sour ce cate gories or ind ivid ual, l arge scale sources, simple cost effectiveness estimates ba sed on a dollar-per-ton calculation may not be as meaningful as a dollar-per -deciview calculation, especially if the strategies reduce diffe rent

groups of polluta

nts.

5.2 Reasonable Progress Statutory Fact or (b): Time Necessary for Com pliance

The second factor is the “time necessar y for complianc e.” It may be appropriate for y

ou to use this f

actor to adjust the

RPG to ref

lect the d egree of improv ement in v isibility achieva ble within the period of the first SIP if the time needed for full implementation of a control measure (or measures) will extend bey ond 2018. For example, if you a nticipate that constraints on the availability of construction labor will preclude the installation of controls at all sources of a particu lar cate gory

by 2 018, the v isibility

improveme

nt anticip ated fr

om installa

tion of co ntrols at the pe rcenta ge of so urces th at could be controlled within the strategy period should be considered in setting the RPG and in establishing the SI P requirements to meet the RPG.

5.3 Reasonable Progress Statutory Fact or (c): Energy and Non-Air Impacts

The th ird fa ctor i s “ener gy and non- air env ironm ental impac ts.” In a ssess ing ene rgy impacts, you may

want to consider whether the energ y require ments associated with a control technology

result in energy

penalties. For example, controls on diesel engines may decrease the engine’s fuel efficiency

, leading to an increase in diesel fuel c onsumption. Or, a particular control may re quire a fuel unavailable in the area. To the extent that these considerations are quantifia ble they should be i

ncluded i n the eng ineerin

g analy ses suppor

ting com pliance cost
estimate s.

Some examples of non-air environmental impacts that y ou may wish to consider, ar e the effects of the waste stream that may be generated by

a particular control technology , and/or other

resource consumption rates such as water, wa ter supply, and wa ste water disposal. To the extent that these considerations are quantifiable, they should also be included in the analy ses supporting complian ce cost e stimates.

For add itional g uidance on apply ing this f actor to stationar y so urces, y ou may wish to consult the BART Guidelines, referenced a bove.

5.4 Reasonable Progress Statutory Fact or (d): The Remaining Useful Life of the Source

The four th statutor

y f actor is “ the rema ining use ful life o f any

existing so

urce sub ject to [reasonable progress] requirements.” This fac tor is generally

best treated as one element of the overall cost analy sis. The “remaining useful life” of a sourc e, if it represents a relatively short time period, may af

fect the annualized costs of retrofit controls. For example, the methods for
calcula ting ann ualized c osts in EPA’ s Air Pollution Control Cost Manual require the use of a specified time period for amortization that varies based upon the ty pe of control. If the remaining useful life of the source will clea rly exceed this time period, the re maining useful life factor has essentially

no effect on control costs and on the reasonable pr ogress determination process. Where the remaining useful life of the source is less than the time period for amortizing
the costs of the re trofit co ntrol, y

ou may wish to use

this shorte

r time per iod in y our cost
calcula tions.
